The solution to the system of equations is x = -1.4 and y = 1.6

How to estimate the solution?

The system of equations is given as:

-3x + 3y = 9

2x - 7y = -14

Divide the first equation by  3

-x + y = 3

Make y the subject

y = 3 + x

Substitute y = 3 + x in 2x - 7y = -14

2x - 7(3 + x) = -14

Expand

2x - 21 - 7x = -14

Evaluate the like terms

-5x = 7

Divide by -5

x = -1.4

Substitute x = -1.4 in y = 3 + x

y = 3 - 1.4

Evaluate

y = 1.6

Hence, the solution to the system of equations is x = -1.4 and y = 1.6
